I just purchased a 3GS today.
I tried searching the forums but the information I found is unclear.
My iphone is locked to at&t and came with 3.1 out of the box.
if I restore a custom 3.1 IPSW using itunes, will it jailbreak?
I am not interested in an unlock so I know redsonw wont work, by question is about using a restore of a custom IPSW.
